Abstract

Selon un aspect, la divulgation concerne un processus de purification de protéines et/ou de protéines hydrophobes qui ont tendance à s'agréger lorsqu'elles sont produites à des niveaux élevés dans la culture cellulaire. Dans un autre aspect, le processus consiste à soumettre des cellules intactes à une base forte dans une solution présentant un pH supérieur à 12,5, avec un prétraitement initial facultatif à un pH supérieur à 13. Le processus fonctionne efficacement avec un chargement de biomasse élevé allant jusqu'à environ 20 % (p/v) ou supérieur à environ 20 % et ne nécessite pas l'utilisation de floculants externes. La protéine cible peut être purifiée par le processus divulgué de manière peu coûteuse et efficace, ce qui permet de produire un produit final de haute qualité présentant peu ou pas de contaminants. Le présent abrégé est destiné à être utilisé comme outil d'exploration à des fins de recherche dans ce domaine technique particulier et ne se limite pas à la présente divulgation.
